TUCKER ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 278,422, dated May 29,1883.

Application filed Apri121,1 882. (No model.) 7

To all whom it may concern: i i

- Be it known ihatwe, AnFRnn A. FISHER .and ALBERT, HART, of the city and county of SanFrancisco, State of California, have in- 5 vented an Improved Tucker Attachmentfor Sewing-Machines; and we hereby declare the following to'be a full, clear, and exact description thereof. i

Our invention relates to a tucker attachment for sewingmachines, and particularly to certain new and useful improvements upon a tucker attachment for which we applied for Letters Patent of' the United States, July 27, 1881, and which was allowed February 27,

which we hereby specially refer.

These improvements consist generally in the arrangement of parts and their construction, having in view the provision of a tucker attachment more nearly approaching perfection than that to which we have referred; and they consist particularlyin anovel means of adjusting the base-plate and the lower or under guard, and. in the particular construction of said guard and-its underlyingtuck-securing plate; also, in a novel means for regulating the Width of the tuck-guiding slot, and in a no'veladjusiable tuck guard or support within the slot; also, in a novel means for adjusting the upper guard, and in adjustable attachments thereto for guidingthe goods to the tucker, and in the means by which this is' accomplished. i

For a more particular explanation reference is hereby made to the following description, and to the accompanying drawings,in which- Figure 1 is a perspective view of thetucker, showing the goods in process of tucking. Fig. 2 is a front elevation of the-tucker. Fig.3 is a perspective view of the tucker with guard open. Fig. 4 is a side elevation of the endof the tucker next the sewing-machine. Fig. 5 is a section through tuck-guiding slot 0. Fig. dis a plan showinggage' and swivel of upper guard. Fig.7 is a plan of the clutch-plate. Fig. 8 is a section through line 1 2 on Figs. 2 and 3.

withdraws or'advances piece'E.

A represents generally the operative. parts of any sewing-machine, showing the needle, presser-foot, 85c. i

G represents the base-plate of the tucking attachment. This issecured to the top of the machine by means of a set-screw through a slot, at. Y

D is the inclined plow-shaped transverse piece secured upon the top of the base-plate.

E is the pieceupon the base-plate having an inclination similar to thatof D. It is secured to plate 0 by means of a slot, through which a stationary screw, b, passes into said plate. It is adapted to move upon said plate to vary its distance from piece D by means of an adj ustingscrew, b, which passes throughits side next to 6 5 piece D intosaid piece. Between the two transverse pieces D'and E is formed the slot '0, which may be suitably adjusted in width by operatingscrew b. which by its movement d represents the guide-plate, which is attached to the inner side, near its lower end, of

piece E, within slot 0, and which lays the tuck flat which travels in slot 0.

F represents the guide or support for the tuck. It consists of a strip of metal, the base of which is straight and lies on base-plate 0. Its top is inclined upwardly toward: the rear. It hasa slotted top guide,f, to direct the tuck, and a horizontal slot, f. It is placed between pieces. D and E in slot 0, and them].-

justing-screw 1) passes through its slotf. By

moving it backor forth across the base-plate O, the distance between its inclined top and the top of pieces D and E may be .varied for different widths of tuck which travel in slot 0. Thus by moving it forward the distance is decreased, and vice versa. It is held in position by the approaching edges of the pieces D and .E and its to hasasimilar inclina ion to said 0 3, 1 pieces.

G is the hinge upon the outer end of piece E, with its side guides, g, in which the end or shank of the upper guard, H, fits. This guard has awide cross end,-h, turned upward at right angles, and is provided with vertical slots h.

H is an angled guard, the upright side of which fits against the upturned end h, and is us heretofore.

.cess in said turn-table plate.

secured thereto by screws k passing through slots It, thus being firmly secured to the upright part of the guard H. The shank of the guard H has a slot, (1, the end of which is enlarged, and is adapted to fitover a thumbscrew, 0, secured in piece E. The operation of the guard H is similar to that explained by By means of its hinge it may turn down upon and slip forward on piece E.

In order to adjust its position in slipping for-v ward, when desirable, we have the sliding stop-plate e, secured by a screw, 6 its end heing'adapted, when set to proper position, to come in contact with the thumb-screw e, and thus to limit the movement of guard H toward the slot 0, where the goods are passing. The upturned cross end h. of guard H is continued upon a level below the lower end of piece E, and is slotted, as'shown. The guard H is itselfcontinued upon a level, and supports a sliding guide, Z, having a slot and secured by a screw, z. This guide is adapted to slide forward through the slotted end of h, and serves as a continuation of the presser-.foot of the machine when such is necessaryby reason of the movement of the tucker to suit various tucks. The guard H is also continued above, and a sliding guide-plate, Z, secured by a screw, is adapt-ed to slide under it, to hold the goods close against the under guard and direct them 'to the slot 0. The other end of the base-plate C fits into side guides under a plate, 0', and has a cross-guide, 0, above said plate, fitting through its slotted end, as shown. Through the cross-guide o a screw, 0 passes. This screw is the end of a rod passing in a suitable channel to the end of plate 0, where it is provided with a pinion, t, with which meshes a gear, 2', operated by a thumb-wheel, I, as

shown. By moving this thumb-wheel the screw-rod. 0 moves the base-plate C in the direction of its length. Byloosening the thumbscrew through the slot a, which secures the base-plate to the sewin'g-machine,said baseplatemay thus be'moved to adjust the position of the slot 0 with reference to the needle.

The plate 0 has attached to its end an upper plate, m, provided with a notch, 7t, which brings up against a stud, it, when m and I are in position to be secured together by the springbolt m, secured to I and adapted to enter a re- Athumb-nu'aj, fits screw 1 and secures the bearing to the guard. The guard and bearing fit over the pivot-pin 7c, and a set-screw secures it. A clutch-plate, m, sliding in guides m upon the inclined plate I, fits its end into the notched end of the bearing-plate m and keepsthe guard J straight. in engagement bya spring, m within a recess in plate I. By moving and holding the clutchplate m back the guard Jmay be swung around or turned out of the way. Byloosenin g thumbnutj' the guard J may be moved in the direction of its length to adjust the distance of-*its cross-heady from the slot 0.

K is the tuck-securing plate under guard J, toward-its inner end, This has a cross-head, q, with a turned-down edge or lip adapted to fit within the slotcits entire length. The adjustment of this plate is accomplished by providing its upper side with beveled flangeguides q, fitted upon and supported by the correspondingly-beveled edges of the guard J. The outer end of the plate K is provided with a screw-pimg which fits through a slot, 0, in the guard J, and is secured by a nut.-

In order to provide for the setting of guard J when it becomes necessary to turn it somewhat upon its pivoted end, and still -to keep its cross-head straight with the slot 0 and its tuck-securing plate K in such position as to keep itslip q within the said slot, we make the guard in two sections, the joint being at Y, whereby a secondary adjustment is had of the upper plate, and the adjustment made with great nicety. Here two screws secure the two sections. When loosened the inner section, carrying the plate K, may be always kept straight no matter what position or inclination the whole guard may be made to assume. The operation of the tucker upon the cloth, when fed to it in the manner we shall presently explain,is precisely the same as we have explained in our previous specification, the changes herein made being simply to effect a better result. The goods are folded around the cross-head j and extend away from the machine, one fold being under and the other above the guard J. The previous tuck which is on the under fold) travels in the slot c. The cross-head j makes the tuck, and its lateral adjustment varies its width. Thus the under guard, J, is adjusted in the direction of its length so thatits cross-head shall extend beyond the needle a distance equal to the width of the tuck to be made. The upper guard,H, is folded down upon and secures the cloth,its upturned cross end fitting against the cross end of the guard J. The angled guard Hmay be adjusted to provide for the thickness of the material, which by passing under it is suitably guided.

When the tuck to be made is very wide, and the goods in passing from under the needle extend to one side of the presser-foot, the sliding guide-plate Z may be adjusted over the goods and properly direct them.

To prevent the goods from sagging down The clutch-plate m is'held I IIS -e maybe suitably set, as explained.

after lea'viiigtthe'frame, and keep them closely up against the cross-head j of 'guardJ, and direct the previous tuck into slot 0, the guide it would have a tendency to bind the goods,:

and thus impede their passage, the stop-plate After the first: tuckiis completed it is made to travel in the slot and furnish a guide for -the width between it and the next tuck.

The adjustment of the. base-plate and ofthe guard J to fixttheposition of the slot 0 withregard tothe needle, and to cause the said guard, with its plate K, to conform to the changed pomeans' herein. described, and for the purpose heretofore explained in our previous specifioa tion. In order to accuratelyidetermine these adjustments, we have a gage, 1", consisting of k U a numberofliues upon the plate 0. The point of the cross-guide c" of thefinain plate C is utilized as a pointer. Theother gage is marked t upon the .endiof the guard J, and to it a;

, a pointer, s, secured by the thumb-nuts jiandt the nut fitting pivot-pin k,'iS directed.

Although werhave heretofore spoken of the: space between the transverse pieces D and E;

as ja tit slotfic, it is obvious that it might be agroove or any suitable channel for directing theittuck which UZNBIS in it. i I 1 We have in our previous specification explained the necessitytfor andthe: operation of a-suitable frame from which and by which the goods-are directed or'fed tovthe tucker. Our;

improvementin this respect consists in a frame i by which an endless band of goods is fed to the device, whereby we are enabled to continue. the tuekin g process without havingito remove; the cloth aftereach' tuck, as wevhave hithertoanew method of accomplishing the tucking process, by means of which we can without interruption tuck a large piece or bolt of cloth.

i The present tucker and the nieanstfor feeding the goods to it are jointly adapted to produce the result.

P is the top of the table, havingan elevated longitudinal bar or portion, 00, the uppersurface of which is on a level with the upper surface of the plate of the sewingmachine, said plate extending to one side and resting against.

the said raised portion or of table P, being secured to the base-plate of the tucker by means of ears and screws 14. P are the legs of the table. In the front of the table is journaled a rollerfQ. Upon its back are secured socketbearings R, in which fit rods R, adapted to be vertically adjusted therein by means of a thumb-nut under the table. In the tops of these adjustable rods is journaled a rod, 1', secured to the directing-board S. This board continues the inclination of the transverse pieces D and E of the tucker, its lower edge approaching nearly to the top of the inclined I tuck-support F,'and thence inclining upwardly to the r rear, as shown. In its upper end is .journaled a roller, S, having a flange upon its inner end. This roller may be jou'rnaled, as shown, in any of the series of notches made in the side pieces of board S.

T is a brace pivoted to the back of the table P, its other end being'engaged in a. rack-bar,

V represents a tension-roller suspended under the board, which may be used for very a 1;, under the board S. This supports the saidi i board and provides for its change of inclina- -tion.

light stuff. Theobject of this construction is r to provide forv the adjustment of the directing board-as follows: The inner edge of the board sition of the? base-plate,is accomplished by the] is very nearly in a line with thecross cndp' of guard J of the tucker, and the flange uponthe .inner edge of roller S defines the limit or fold of the'goods. When the guard'J is moved to make a different width-of tuck, as explained, the directing-board mustalso be moved laterally to keep its position with reference to said guard. Thisit can do by reason of the rodrfl} is being made, soas to support the goodsin 'a' position high enough to direct the tuck within slot 0. "This is accomplished by the vertically adjustable rods It.

The inclination of'the board is changed by the brace T to cause it to conform to the inclination of the pieces D and E after said board has been verticallyad' justed. i

Let W represent the goods. This is made in an endless band by properly securing the two ends. directing-board S to the tucker, over roller Q,

and under the table, up again to roller S. been compelled to do. We have thus effected;

When the tension-roller Vis needed it maybe passed over it. As the tucking progresses It'passes over roller S, down the the part tucked is turned under, and i when I once started willcon'tinue. t The cloth advances .asthe machinedraws it, and the tuck is con- -tinuous, as are the threads ofa screw, for the portion or part of tuck previously made is constantly passing through the slot 0, and the cross-heady of guard J always folds it over until the piece of goods is finished in one con" tinuous tuck. 1 t

If we should not desire to feed the goods to the tucker in an endless band, we could fold the bolt upon a table under the board S, and carry it up over the roller S and deposit it in front.

Having thus described our invention, what weclaim as'new, and desire ters Patent, is-
